BW-21 Boiler Treatment |
|
BW-21 Boiler Treatment is a supplemental dry sulfite. This product is not USDA approved. BW-21 Boiler Treatment reacts with the oxygen found in feedwater to form a chemical compound, thus tying up free oxygen. By deactivating free oxygen, BW-21 prevents the localized oxygen-induced corrosion known as oxygen pitting. |
